CARL EIVIIL ANDERSSON, OF ESKILSTUNA, SWEDEN, ASSIGNOR TO AKTIEBOLAGETESKILSTUNA SEPARATOR, OF ESKILSTUNA, SWEDEN.

PRESSURE-BURNER WITH COMPRESSED MIXING-PIPE.

To all whom it may concern:

Be it known that I, CARL EMIL ANDERS- SON, a subject of the King ofSweden, and a resident of Eskilstuna, in Sweden, mechanician, haveinvented a new and useful Pressure-Burner with Compressed Mixing- Pipe,of which the following is a specification.

This invention refers to pressure burners for petroleum and similarfuels and has for its object to hinder the flame from turning backwardand to reduce the shade field caused by the mixing tube. These objectsare attained essentially by using a compressed or flattened mixing tubethe lesser diameter of which is perpendicular or nearly so to thedirection of the rays of light radiating from the flame and crossing thetube.

l/Vhen using a small tube for introducing alcohol or the like forpreliminarily heating the burner by means of an alcohol flame thisalcohol tube may preferably be arranged within the mixing tube so as tostill more reduce the free section of the mixing tube in certaindirection.

In the accompanying drawing Figure l is a plan View and Fig. 2 a sideview of a burner with such an arrangement. Fig. 3 is a horizontalsection of the mixing tube on line AA of Fig. 2. r

In the form shown on the drawing the mixing tube 1 is compressed orflattened in such a manner, that the section forms a rectangle withrounded or obtuse corners, but any other compressed form may be used ifpreferred. The largest diameter is directed toward the center of light.The inwardly directed lower end is as usual connected to the centralpart 3 of the burner.

4 designates the usual alcohol cup which may be filled by means of thesmall pipe 6, the upper mouth 5 of which is enlarged to Specification ofLetters Patent.

the shape of a funnel for facilitating the pouring. A part of this pipe6 is placed in the mixing tube and the lower part which extends throughthe wall of mixing tube forms a perforated ring pipe 7, from which thefluid trickles down in the cup. Wicks 8 hanging down from this ring-pipewill enlarge the surface from which vapors of alco hol are given ofl andthus reinforce the combustion and quicken the lighting.

By means of the plate 2 or by any other suitable means the burner isfastened on its place.

For the sake of clearness, the vapor generator and the fuel feedingdevice are not herein illustrated, but it is to be understood that thesemay be of any of the well-known or approved forms of construction, noclaim thereto being made in this application.

What I claim is:

1. In a pressure burner for petroleum and the like, a flattened mixingtube disposed with its greater diameter toward the center of light, anda pipe extended for a portion of its length within said mixing tube withits lower end extended through the side wall of said tube and having aportion encircling the burner.

2. In a pressure burner'for petroleum and the like, an alcohol cup, aflattened mixing tube, a pipe extended within said mixing tube andhaving a portion encircling the burner, and wicks depending from theannular portion of said pipe into the alcohol cup.

Intestimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CARL EMIL ANDERSSON.
